AC drives increase production and save energy for cement producer

摘要

One of Europe's most modern cement kilns, at Castle Cement's Padeswood works in North Wales, is being speed controlled by two, 300kW ABB industrial drives The drives work in master-follower 11 arrangement. Here, both drives have an individual gearbox which m in turn drives a common girth gear that is attached to the kiln shell. The benefits of this arrangement mean that the speed of the drives change as the kiln feed increases or decreases. "This speed control is essential for the quality of the product," stresses Castle Cement's plant electrical engineer, Dave Jones.
